【问题描述】：
我在 view.py 中将元组列表从视图传递到模板，如下所示：
def index(request):
page_index = int(request.GET["page"])
s_page = (page_offset*page_index) + 1
e_page = (page_index + 1)*page_offset
user_statuses = get_user_status()
user_statuses.sort(key=lambda user_statuses: datetime.datetime.strptime(user_statuses[0], '%Y-%m-%d'),reverse=True)
print user_statuses
user_statuses = user_statuses[s_page : e_page+1]
print user_statuses
return render(request, 'view_status.html', {'lists': user_statuses,'next_page':page_index+1,'prev_page':page_index-1})
user_statuses 是元组列表。
下面是我的模板：
<body>
<div ng-app="appTable">
<div ng-controller="Allocation">
<h2><span>VIEW STATUS</span></h2>
<a ng-href="/welcome_page/">Return to Welcome Page</a><br><br>
Select start date:
<input type="text"
datepicker
ng-model="start_date" />
<br>
<br>
Select end date:
<input type="text"
datepicker
ng-model="end_date" />
<br>
<br>
<button ng-click="Submit()"> Submit </button>
{%verbatim%} {{error}}{%endverbatim%}
{%verbatim%} {{msg}}{%endverbatim%}
<br>
<table>
<th bgcolor="#35a5f0">
<td bgcolor="#35a5f0">Date</td>
<td bgcolor="#35a5f0">Project</td>
<td bgcolor="#35a5f0">Release</td>
<td bgcolor="#35a5f0">Feature</td>
<td bgcolor="#35a5f0">Module name</td>
<td bgcolor="#35a5f0">Hours spent</td>
<td bgcolor="#35a5f0">Comment</td>
</th>
</thead>
<tbody>
{%for list in lists%}
<tr>
{{list.0}} {{list.1}}
<td><input type="checkbox" ng-model="data.isDelete"/></td>
<td>
<div ui-view ng-init="data.date='{{list.0}}'" >
<input type="text"
datepicker
ng-model="data.date" />
</div>
</td>
<td>
<div ng-init="data.dept='{{list.1}}' " >
<input type="text" ng-model="data.dept" />
</div>
</td>
<td>
<select ng-model="data.release" ng-options="x for x in range">
</select>
</td>
<td>
<select ng-model="data.feature" ng-options="x for x in feature">
</select>
</td>
<td>
<input type = "text" ng-model = "data.modulename">
</td>
<td>
<select ng-model="data.hours" ng-options="x for x in hours">
</select>
</td>
<td>
<input type = "text" ng-model = "data.comment">
</td>
</tr>
{% endfor %}
</tbody>
</table>
<a ng-href="/view_status/?page={{prev_page}}">Previous</a>
<a ng-href="/view_status/?page={{next_page}}">Next</a>
</div>
</div>
</body>
这是我的 AJ 脚本：
<script>
var app = angular.module("appTable", []);
app.controller("Allocation", function($scope, $http) {
$scope.start_date = "2017-05-01";
$scope.end_date = "2017-05-19";
$scope.data = {}
$scope.hours = ["1", "2", "3"];
$scope.range = ["1", "2", "3"];
$scope.feature = ["UT", "FSDS", "Coding", "QA"];
$scope.postData = function(s_date, e_date) {
console.log('post called');
var data = {
s_date: s_date,
e_date: e_date,
};
console.log(data);
$http.post('/view_status/', data).then(function(response) {
if (response.data)
$scope.msg = "Data Submitted Successfully!";
}, function(response) {
$scope.msg = "Service not Exists";
$scope.statusval = response.status;
$scope.statustext = response.statusText;
$scope.headers = response.headers();
});
};
});
app.directive("datepicker", function() {
function link(scope, element, attrs, controller) {
// CALL THE "datepicker()" METHOD USING THE "element" OBJECT.
element.datepicker({
onSelect: function(dt) {
scope.$apply(function() {
// UPDATE THE VIEW VALUE WITH THE SELECTED DATE.
controller.$setViewValue(dt);
});
},
dateFormat: "yy-mm-dd" // SET THE FORMAT.
});
}
return {
require: 'ngModel',
link: link
};
});
</script>
view.py 中字典 user_statuses 的值如下：
[(u'2017-05-02', u'p2', u'1', u'UT', u'pqr', u'1', u'Add extra information'), (u'2017-05-01', u'p1', u'1', u'UT', u'abc', u'1', u'Add extra information')]
当我打印 {{list.0}} 和 {{list.1}} 时，您可以看到它显示了正确的输出。 但是，当我使用 ng-init 使用相同的值在表中显示时，它会在两行中显示相同的值，这就是问题所在。 请帮忙。
【问题讨论】：
-
控制台是否显示任何内容
-
不。它什么都不显示
-
是的，它正在按预期更新。即...
